KNOW ALL MEN B Y THESE PRESENTS:

That I, CHARLES-E. PIERCE, of the city, county, and State of New York,have invented certain new and 'useful Improvements in Burglar-AlarmApparatus, andwhich I design to be used in' connection Awith doors,

gates, windows, and shutters, andto'be so placed and arranged that whena door, gate, window, or shutter with which my said burglar-alarmappa-ratusris connected, is slightly opened or raised, an alarm will besounded, and indicato onthe dial-plate which door, gate, window, orshutter, or apartment of building is being opened, raised, or disturbed,and at the Isame time lock said door, gate, window, or shutter, as .casemay be. The following is a full, clear, and exact description thereof',reference being had to the annexed drawings, making a 'part of the same,in whichfy Figure 1 represents a side view of the alarm-mechanism, andFigure f?, a top viewot` the'saine Figure 3 represents the dial-plate.Figure 4 represents ya. front view of a case which encloses thealarm-mechanism. Figures 5 and 6 represent the window-guards or bolts,which are tobefastened to a window-frame, and Figures 5 and 6" thefrontV andV side view ofv a plate to be fastened to Va. window-sash.Figure 6? represents a knob to be placed on the outer ends ofwindow-guards or bolts. Figure 7 represents a perspective view oi' abolt for doors, gates, and shutters, and I v Figures 7 and 7* the frontand side view of a plate which is fastened to thejamb of a-door, gate,or shutter. Figures 8 and 8* represent a front and side view of a lever.i y y Figures 9 and 9 represent a crank to be used in connection withthe alarm-apparatus. Figuresv'lt), 11, 1 2, and 12 represent a front andside view of rollers, to be used in connection with the alarm-apparatns.I I

I Figure 13 represents a lever to be attached to the alarm-mcchanism; L,on Figures l14, 145, 14", and 14,

`represent parts oi' a movement Whiclrisapart of the alarmmovemcnt Allof which said figures above mentioned are more minutcly' described andexplained below. K

Only one alarm-movement, with its propcrvattaehmcnts, on plate A, isrepresentedin the drawings,-but in thc construction and application ofmy said burglar-alarm apparatus, as many alarm-movements, ,with movementL and lever O attached,may be used a's desired, being careful to placeeach. alarm-movement in suitable relation to and around the alarm-helland armsattachcd to the centre-wheel, said movement and bellbeingfastened on plate A.

b, on figs. Sand 6, respectively represent thc arms attached to theguards or bolts for the connectingwires or lines, and to the outer endsof which the said wires or lines may be attached. Said wires or linesmay bc attached to either ends of said arms I, depending upon thedirection of turn .given to the bolt, with which they are respectivelyconnected.

C, on figs. 5 and 6, represent the guards or bolts for windows, and c cthe knob on said bolt, which is placed on and near the end of said boltC. i

D, on iig. 6, is a small knob, which is to be placed. or vscrewed on tothe outer end of said bolt C, said i nob'l) projecting through the frameand into a room, for thc-purpose of its being clasped hold of, or todrawA said bolt-knob c/c out and away from the cavity or recess in plateor figs. 5 and '6"; said plate being fastenedl z to n. window-sash. Whensaid bolt-knob c e is drawn away or removed from the recess inplate onfigs. 5 and 5", hereinafter described, which is attached to a sash, thesaid sash becomes unlocked, andis free to bejraised or lowered, as thecase may be, without disturbing the alarm-mechanism, which is placed ina sleeping-apartment or other part of albuilding. i l K i E, on figs. 5and 6, is a plate, made of metal or other suitable material, to whichthe holtC is fastened; said plate E having a slot-in it, near thc formof an L, and through whichprojects knob c c, and let into the recess orcavit'yn plate or figs. 5 and 5b, said plate being fastenedto awindow-sash. i

F is tho cavity-on plate 5 and 5", for knob e c to hcinscrted yas abovedescribed, when pressure is made against knob ce, attached to the boltC, hy'raising or lowering the window-sash,- the object being tocauseapull to be made on the connecting-wires or lines, and opcratelcver O,onfig. 13, attached to the alarmconcealing the name of a door, gate,window-shutter, or apartmentof a buildil|g,'ivliicl1 may be written orplaced iu its proper place on dial-plate on iig. 3, Y i

In the use of my said alarm and lock-apparatus, it will be' found moreconvenient and desirable to have the parts thereof which are enclosed inthe case or cover, above described, placed in some convenient; localityof a sleeping-room, or apartment of a building, so that 'when 'anattempt is made by a burglar or other person to open a door, gate,window, or shutter, when the said apparatusis properly adjusted, analarm will be sounded and immediately indicate on the dial-plate thename of the door, window, gate, shutter, or apartment of c, buildingwhich is being disturbed. To effect the locking of the door and alarmbeing sounded, also indicating on the dial-plate from whence the alarmproceeds, one end of wires 1or lines is attached to one end of lever O,or its equivalent attached to the alarm-movement, and the other end of'thc said wires or lines is fastened to the outer ends of the guards orbolts, above described; and when the knob of either of the window ordoor-bolts is placed in the recess or cavity in platcs on gs. 5 and 5b,and 7 and 7b, said plates being fastened to a door, gate, sbutter, orwindow, by slightly raising or lowering the window, or opening the door,gate, or shutter, it will cause the bolt teturn partially around,carrying with it the arms bien the bolt Gand C', to which theconnecting-wires or lines are attached, andconsequently cause said.wires orlines to draw down that arm of the lever 0 attached to thealarm-movement with which cneend ofthe wires orlines is connected',which raises the opposite arm of lever 0, and releases the projectingpart o o from the detect-army', attached te spindle g', said spindle gbeing attached to the alarm-movement. The projecting part o o o beinginserted in clasp Lion spindle Ll, and one end of lever O being, raised,of course carries with-it'the outer end of clasp L2. The pin L3, onspindle Ll being inserted-in clasp L, attached to spindle L L, causessaid spindle L L tc turn to the right or left, carrying with it hand G,which is fastened to the upper end of spindleL L, which projectsvthrough the dial-plate, above described. The object ci' said hand Gbeing placed over the dial and'nttached to spindle L L, is for the purapose o-rovealing or concealing the name of the window, door, gate,shutter, or apartment of a building, and when arm m', attached tocentre-wheel m, is moved out and away fromA the detenbarm q, and theprojecting o o, lever O raised also out of the way of the detect-arm q,attached to spindle g', theihammer-arm P attached to spindle q becomesfree, and when the spring, attached-to the alarm-movement is wound up,an alarm will be sounded, hand G turned so as to reveal ou thedial-plate the name of the door, gate, shutter, window, or apartment ofa buildingl which is being disturbed and causes the alarm.

" Having thus described mysad alarm and lock-apparatus, and the mannerIin which the same is operated, what I claim as new therein, and desireto secureby Letters Patent, is-e v i 1. :I claim the combination of thebolts shown in figs. 5 and 6, with the parts 5", 5, and 6, operating tovlock a window, in the manner shown.

2. The parts represented onigs. 14, 14, 14?, and 14,, or theirequivalent, operating as described and for the purposes set forth. Y i

3. In combination with theelements ofthe preceding claim, I claim thelever A0, operating as described; 4. In combina'tionpwith thealarmanechanism, I claim the levers for increasing the length ofmovement, and the rollers, all combined as and for the purposes setforth.

5. I claim the centre-wheel M, on figs. 1 and 2, madeup of parts Ml andMi, for purposes set forth. 6. I claim the bolt' on lig. 7, made up ofparts C', I, b', and K, for locking a door or gate, at the same timethat it operates the alarm-mechanism, as described and for purposes setforth. Y

7. In combination with elements of the claim preceding, I claim theplates .I and IIfas and for the pur' peset set forth. I

, 8. In combination with the parts claimed in the second and thirdclaims, I claim the dial-plate with open= ings, as and for the purposesset forth. v
